teleprompter for GY-HM100

I have a shoot coming up in a couple months and the client wants a prompter. my gut reaction is to hire a prompter service to come in and handle it, but since I'm using my little GY-HM100 I'm tempted to get one of the ipad or iphone prompters that I have read about.

curious if anybody has used one with this camera and if anybody can recommend a good one.
